To remove them you would need to modify compiler to use its own
constraints logic instead of native .NET generics, which I'm not
really sure is worth doing. Otherwise you could just hide the needed
casts and type-checks behind generated code - thus making it more safe
for users.

I think that building a nicer syntax and generating parts of the
boilerplate code by macros would be quite interesting extension of
your implementation :)
